FEATURED NEOLOGISM:

To hallucinate / halucynować: to say incorrect or misleading things. Initially used in the context of large language models (LLMs), it is now also applied to humans, not in the literal sense of experiencing hallucinations, but to describe expressing incorrect or nonsensical information. For example: “Ale ona gada głupoty – ciągle się zapętla, chyba halucynuje.” (She’s talking nonsense – she keeps repeating herself, she must be hallucinating.)
